Biotin, is a vitamin which is B-complex in nature and is water soluble. Biotin helps in transferring carbon dioxide along with helping in various metabolic reactions. A steady blood sugar level can also be maintained by the help of biotin. Hair and nails are strengthened by the consumption of biotin. Therefore, a lot of hair and cosmetic products use biotin as one of its ingredients. The body’s daily requirement of vitamin B7 is produced by the intestinal bacteria. This therefore reduces the chances of vitamin B7 deficiency. There a large number of foods that contain biotin in large quantities. Swiss chard, tomatoes, liver,eggs, almonds, cumcuber, cauliflower, legume, soybeans, raspberries, carrots are some of those foods.

Calcium, is necessary for many bodily functions, such as muscle contraction, and proper heart function.

Chromium is a natural trace mineral in human nutrition and is needed for proper metabolism of sugar in humans. It is vital for metabolism of fats and carbohydrates. It helps move blood sugar from the bloodstream into cells to be utilized as energy and turn fats, carbohydrates, and proteins into energy. Chromium helps stimulate fatty acid and cholesterol synthesis and activates numerous enzymes that are required to drive many chemical reactions essential to life. Chromium supplements also improve glucose tolerance in people with Turner's syndrome, a disease associated with glucose intolerance. It is also vital for insulin metabolism.

Copper is being considered a mineral with immense medical advantages, copper has been used as a supplement in its gluconate form and is used in this form in gaspari nutrition intrapro. Copper is one of the most important constituents of the blood and prevents poly – unsaturated fatty acids from turning rancid. Copper also increases the health of the cell membranes and is actively involved in the formation of hemoglobin. Copper Gluconate is instrumental in treating conditions such as irregular beating of the heart, hypoglycemia, osteoporosis, osteoarthritis, and in lowering the cholesterol levels of the body.

Folate belongs to the B complex group, which is vital for metabolic processes in the body. It decreases levels of amino acid homocysteine in the body, ensuring protection against heart ailments. It also reduces the risk of neural tube and other birth defects like cleft lip and palate, and various congenital heart defects. It provides protection against different forms of cancer and heart disease. It is beneficial in treatment of megaloblastic anemia. It also works as a coenzyme in transfer of formyl and hydroxymethyl groups in various biological systems, and in carbon metabolism. It assists the body in getting rid of homocysteine, a blood toxin affecting heart muscle and making cholesterol deposit in heart muscle. It also prevents stroke and heart attack.

Iodine, a necessary element used by the body to make the thyroid hormones thyroxine and triiodothyronine. These Thyroid hormones are needed to maintain a healthy metabolic rate and cellular metabolism.

Iron is a necessary mineral for humans, needed for example to help form red blood cells which transport oxygen around the body. Fortunately there are plenty of good sources available for both the omnivore and the vegetarian or vegan These include liver, meat, beans, nuts, dried fruit , also whole grains and many of dark green leafy vegetables, although some such as spinach also contain substances that prevent the absorption of iron as do caffeine based drinks such as tea and coffee. On the other hand the drinking of fluids containing vitamin C aids the body in its necessary task of absorbing iron.

Magnesium is essential to all living cells and is a vital component to a healthy diet, the calcium absorption from gaspari nutrition intrapro depends on magnesium to facilitate this.

Manganese is a trace mineral that has long been associated with musculoskeletal health. It activates enzymes in the body that is necessary for the production of collagen and proteoglycan, components of connective tissue. It also aids in the absorption of calcium in the body. It helps prevent the development of osteoporosis and osteoarthritis. Manganese helps in the digestion and utilization of vitamin E in the body that makes it a potent antioxidant.

Molybdenum is a micromineral needed by the body for the metabolism of purines, a protein component of the DNA. Microminerals are minerals required by the human body in minute amounts (<0.005% of body weight) for enzymatic reactions. These are also known as trace elements. Molybdenum, although needed and present in the body in small amounts, it is as significant as the B-complex vitamins and Magnesium. It is excreted in the urine. Molybdenum toxicity has not been observed in humans but high intakes of molybdenum can alter the activity of alkaline phosphatase and produce bone abnormalities. Doses above 10-15 mg each day causes gout-like symptoms.

Niacin, also called Vitamin B3, is a water-soluble vitamin needed for the conversion of food into energy so that it may be used by the body. Niacin also helps metabolize protein, sugar and fat and is needed, so it is good to have in gaspari nutrition intrapro.

Pantothenic Acid is thought to reduce lactic acid accumulation in athletes, may improve oxygen utilization efficiency, and is believed to improve the body's ability to heal and possibly help in reducing acne

Phosphate (Phosphorus) is the chemical element with the atomic number 15 in the periodic table. It is not found as a free element anywhere in the world. In biology and biochemistry it may be the most important element, being present in all living cells of living species. It is present in the DNA, in the RNA, in ATP, but is also found in cell membranes in form of phospholipids. It is also present in the bones, where it builds calcium phosphate salts, responsible for strong bones. Apatite is a collection of phosphate minerals which are generally found in bones and teeth; namely bromapatite, fluorapatite, chlorapatite and hydroxyapatite.

Potassium is one of the essential minerals required for proper physiological functioning of the body. It plays an important role in the regulation of heart muscles. It helps to convert glucose to glycogen. Glycogen is essential for muscle formation. Potassium also helps to propagate nerve impulses by exchanging ion within cells and also helps in muscle contractions. It helps in balancing blood pressure. It controls the proper functioning of kidney. An average adult needs 3-5 gm of potassium daily. Due to deficiency of potassium, body observes tiredness. Other deficiency symptoms are weakness of muscles, low blood pressure, vomiting, poor kidney functions and Heart arrhythmias. Severe potassium shortages quickly direct to electrolyte disproportion which involves malfunctioning of nerves, kidney and heart.

Riboflavin, also called Vitamin B2, is naturally manufactured by the body. Riboflavin is needed for the proper use of oxygen and amino acids, carbohydrates and fatty acids. Riboflavin is also utilized by Vitamin B6 in the body and is used to manufacture niacin. Riboflavin is especially needed when eating large amounts of protein.

Selenium plays an important function in the antioxidant enzymes that protect cells against free radicals. Selenium also promotes proper thyroid hormone metabolism.

Sodium is part of the extracellular fluid of many multicellular creatures, not least mankind. It is needed for instance in nerve conduction and to balance the acid levels in the body. It is necessary for the functioning of organs such as the liver, intestine and kidneys in their work of ridding the body of toxins However there is an optimum intake. Also an excess of salt in the diet will draw fluid out of the cells by the process of osmosis. On the other hand a lack of sodium will lead to too much water in the body the brains cells will actually be flooded.

Thiamine is a water-soluble vitamin with no known toxic effects if taken with other members of the vitamin B complex. Thiamine is essential to a strong appetite and to enable the body to use sugars and other carbohydrates.

Vitamin A is needed by the retina of the eye in the form of a specific metabolite(the light-absorbing molecule retinal). This molecule is absolutely necessary for both scotopic and color vision. Its defeciency can cause blindness. Other problems include impaired immunity, hypokeratosis (white lumps at hair follicles), keratosis pilaris and squamous metaplasia of the epithelium lining the upper respiratory passages and urinary bladder to a keratinized epithelium.

Vitamin B12- Also called Riboflavin, B2 is a water absorbed vitamin of which the body must replenish its supplies each day as it cannot be stored. It is necessary for the production of red blood cells and, like the other B vitamins, it works at supporting it supports energy production by helping in the metabolism of various foods.B2 is required for healthy skin as well as hair growth, the nails and has a role in regulating the activity of the thyroid gland. It is also necessary in order that the body can process amino acids found in proteins and fats and to activate vitamin B6 and folic acid.

Vitamin B6 contains pyridoxal phosphate, or PLP for short, as the active ingredient and is a vitamin belonging to the B complex grouping. It is functioning mainly as a co-enzyme with others in the human body, aiding in the proper function of several metabolic processes. Neurotransmitter synthesis, as well as hemoglobin and histamine synthesis are just some of the functions of PLP, hemoglobin function, gene expression and aiding in the facilitation of decarboxylation, elimination and other reactions, mainly taking place in the liver. Vitamin B6 was found to diminish by 50% the risk of Parkinson’s disease. Alternative medicine suggests the use of Vitamin B6 to combat autism, in combination with magnesium.

Vitamin C is well known for its powerful ability to help boost the immune system as well as fight off damage causing free radicals. As an anti-oxidant, vitamin c binds with free radicals, preventing them from damaging cells.  Vitamin C is integral to cellular metabolism as well and a lack of vitamin C can cause a myriad of issues, including scurvy.

Vitamin D is a group of related sterols with anti-rachitic properties, or “which that prevents rickets”. About 16 forms are known but only two are important in human nutrition. Vitamin D2, also known as ergocalciferol or irradiated ergosterol, is found in lipid portions of plants. Vitamin D3, termed otherwise as cholecalciferol or irradiated 7-dehydrocholesterol, is the substance formed on the skin upon exposure to the ultraviolet rays of sunlight. From this, the name “sunshine vitamin”. It is, however, erroneous to say that vitamin D comes from sunlight; instead, the sunlight activates the vitamin D precursors named earlier. This fat-soluble vitamin is responsible for the normal bone and teeth development because it facilitates the absorption of calcium and phosphorus. Given this function, it is helpful to take in calcium supplements with vitamin D so as to promote proper absorption and utilization of the mineral. Minimum requirement of vitamin D is met by having dairy products, salmon and sardines, and egg yolk in the diet. Fish liver oil is the most concentrated source of vitamin D but is only used in medical and therapeutic purposes. Normal exposure to sunlight, preferably at 6 to 9 AM and 4 to 6 PM would be enough for precursor activation.

Vitamin E is an antioxidant that is known for protecting the tissues of the body from damage caused by free radicals.

Zinc is an essential mineral that is used in many healing processes to speed up the healing process in instance that include sunburned skin, diaper rash and helps prevent premature aging of the skin.

In my opinion gaspari nutrition intrapro protein shakes are in the middle range for taste, Intrapro is a very fine powder and has a thicker, gritty taste, but much better than some of the other powders, I would recommend using less than stated in the directions, unless you like a very thick protein shake. Intrapro makes a great stack with a strong testosterone booster like BigNutrition Adalift is you are going for big gains in the gym.
